Abstract: Disclosed is a battery pack, which includes a plurality of stacked cells; a board assembly including interconnect circuit boards (ICBs) arranged corresponding to cell leads; an ICB cover detachably coupled to the board assembly; and a magnet installed at the ICB cover and coupled to the ICB by a magnetic force thereof with the cell lead being interposed therebetween, wherein the lead is closely fixed to the ICB by means of the magnetic force acting between the ICB and the magnet.

Abstract: A method and device for determining an output of a visible frame in at Visible Light Communication (VLC) device are provided. A first VLC device determines whether to permit a second VLC device to generate visible frames, and transmits, to the second VLC device, visible frame information indicating whether the second VLC device is permitted to generate the visible frames.

Abstract: Disclosed is a Ringer solution infusion controlling apparatus which enables the infused amount and infusion state of a Ringer solution to be easily monitored by an administrator and which automatically blocks infusion of the Ringer solution when the infusion of the Ringer solution is completed.

Abstract: Provided is a silicon blanket for a micro pattern offset printing that includes a first layer wherein the solvent absorption rate has been enhanced by elevating the proportion of low vinyl polysiloxane and adding silicon gum; and a second layer wherein the mechanical strength has been enhanced by elevating the content of high vinyl polysiloxane; thus, increasing the lifetime and initial printing quality.

Abstract: The present invention relates to a conductive paste composition. The conductive paste composition includes a binder resin including a urethane group present in a main chain or a side chain, especially a binder resin formed from isocyanate and a polymer with at least one hydroxyl group, a fine powder, a glass frit, and a solvent. The conductive paste composition can have a superior physical property, improve productivity and an environmental problem by reducing waste fluid such as aqueous alkaline solution, and form a fine pattern having an improved structure. Accordingly, the paste composition is especially useful for a paste for gravure offset printing.

Abstract: A UV-curable and foamable resin composition comprising a photopolymerizable urethane acrylate oligomer, a photopolymerable monomer, a photo polymerization initiator, a photolytic foaming agent selected from an azo compound, a combination of sulonium salt and an inorganic carbonate, and a mixture thereof, and a photolysis catalyst is useful for coating a fiber or ribbon bundle to be applied to an air blown fiber system.

Abstract: A brush assembly comprises a body having a dirt suction port formed thereon, a cover connected with an upper portion of the body to form a suction passage and a turbine chamber, a turbine mounted in the turbine chamber, and a brush drum being rotated by a rotational force received from the turbine. The turbine chamber and the suction passage are partitioned from each other, and the turbine is rotated by an air drawn in through an air suction port which is separated from the dirt suction port. Accordingly, the turbine is prevented from being clogged by dirt, dust or hair.

Abstract: An articulative extension pipe for a vacuum cleaner has a first extension pipe having a joint, a second extension pipe having a joint receiving part in which a joint of the first extension pipe is inserted, a sealing cover enclosing the first and the second extension pipes, and a locking button disposed between the sealing cover and the first extension pipe, and having at least one coupling protrusion on the outer circumference. One of the sealing cover, and the first and the second extension pipes has at least one coupling recess in which the coupling protrusion of the locking button is selectively inserted so that the first extension pipe can rotate with respect to the second extension pipe. The sealing cover further includes a wheel, which rolls in contact with the surface being cleaned, and a cotton flannel is disposed on the outer circumference of the wheel.

Abstract: The present invention relates to a method for preparing a GI (graded index) plastic optical fiber preform having a radial refractive index gradient, the refractive index increasing gradually from the outer periphery of the preform toward the center thereof, comprising inserting a 1st plastic tube (inside diameter: d1i, outside diameter: d1o) (111) made of a first polymer (refractive index: n1) in a cylinder reactor (inside diameter: d0i, d1o?d0i) and inserting a 2nd plastic tube (inside diameter: d2i, outside diameter d2o, d2o?d1i) (112) made of a second polymer (refractive index: n2, n2?n1) in the 1st plastic tube, the reactor, the 1st and 2nd plastic tubes are positioned coaxially, injecting a precursor of a third polymer (refractive index: n?, n??n2) into the 2nd plastic tube, injecting a precursor of a fourth polymer (refractive index: n?, n1?n??n2) into the space between the 1st and 2nd plastic tubes.
